minimise the shock of impact and should have guiding skirt boards spanning the space from two to three troughing idlers to allow the load to settle and adjust itself on the belt before it passes the confines of the skirt boards. Triangular cleats should run

FIG. 3.—Typical belt-conveyor arrangements.
the full length of the skirt boards to assist in properly distributing the load arid the distance between the skirt board should be several inches less than the width of the conveyor belt, depending upon the width of the belt.
Speeds of belt conveyors vary greatly from 40 to 50 ft. per minute for picking anb sorting conveyors to several hundred feet. Heavy material, as a rule, can be conveyed at a higher speed than light material.
Belt conveyors are limited in their ability to carry loads up an incline of much more than 20 deg. and have to be erected in one vertical plane—U, cannot turn corners— though a series of conveyors can discharge from one to the other, each running in a
